When you run smbd -V on your Snow Leopard installation, you'll see it's running SAMBA version 3.0.28a-apple. While I'm not sure how much difference the "-apple" makes, version 3.0.28a is old. Very old. In other words, it's riddled with bugs. Apple hasn't updated SAMBA in 3 years, and for Lion, they're dumping it altogether for something homegrown. The reason? SAMBA is now GPLv3.

If you want to hire a doctor for an opinion and not actual surgery, then likewise hire a software architect to tell you how to build your own friggin' word processor. Both will expect to be paid. That's NOT what you're paying for when you buy a copy of Word.

If you want to hire a drug company to research / invent new drugs for you, expect it to cost a lot and assume you're going to be trying to set up ways to cover the R&D costs, unless of course you're independently wealthy, in which case you can of course espouse communism in whatever profession you want.

Or maybe you're thinking of an author who expects to be paid per copy of his book even if you feel like you could write it yourself or edit certain sentences - or re-print it yourself if the publisher goes belly up?

The software communism crap is just ludicrous.

You are, of course, under the old tired wrong assumption that developing FOSS inherently means not being paid.

Just in case you didn't notice, FOSS relies on copyright. That is, you know, ownership. The kind of thing you don't have with communism.
